LAMP-HOUSE.

Specification of Letters Patent.

Patented Mar. 1, 1921.

Application filed July 5, 1919. Serial No. 308,694.

To all whom it may concern Be it known that I, Lnwrs A. HOBERDIER, a citizen of the United States, 'residingat Canton, in the county of Stark and State of Ohio, have invented a new and useful Lamp- House, of which the following is a specification. I v j The. invention relates to adjusting mechanism for lamp houses and has more especial reference to the adjusting-mechanism for the lamp and reflector within the lamp house.

The objects of the present invention are to provide a universally adjustable lamp carriage and reflector adjusting mechanism; to provide an adjusting mechanism which makes the lamp house readily adaptable for .use as a spot light; and to provide a simple and eflicient construction which may be easily and readily operated and quickly adjusted.

With these objects in view the invention consists in the novel construction and. ar-

able lamp carriage and the reflector adjust-' ing mechanism.

Fig. 2 is a transverse vertical sectional view through the lamp house.

Fig. 3 is a perspective view of the adjustable lamp carriage.

Fig. 4 is a sectional view of the lamp socket.

Fig. 5 is a rear elevation of a portion of the lamp house showing the reflector adjusting mechanism.

Fig. 6 is a top plan view of the reflector adjusting mechanism showing a portion of the lamp house in section.

Fig. 7 is a detail sectional view of the horizontal adjusting means in the reflector adjusting mechanism.

Fig. 8 is a longitudinal vertical section through the lamp'house showing the mechanism adapted for a spot light.

Fig. 9 is a perspective View of a portion of the lamp carriage.

Fig. 10 is a plan view of the reflector adjusting mechanism.

A practical embodiment of the invention is disclosed in the accompanying drawings, forming a part of this specification in which similar numerals of reference indicate corresponding parts throughout the several views.

In Figs. 1 to 7 inclusive are illustrated the lamp carriage and the reflector adjusting mechanism. The lamp is adjustable longitudinally and transversely in the lamp house in a horizontal plane, and is also adjustable vertically. A radial adjustment is also provided upon the lamp socket. A vertical adjustment of the reflector is provided as well as a horizontal longitudinal adjustment and radial adjustment. I

'A pair of. spaced rods 41 extend longitudinally of the lower portion of the lamp house and are carried by the .frame members 42 which are fixed within the lamp house. The lamp carriage generally indicated by the numeral 43 is slidably mounted upon these rods and comprises the end members 44 connected by the side rails 45, lugs 46 being provided with suitable bearings by means of which the carriage is slidably mounted upon the rods 41. A set screw 47 the carriage by meansof a screw 50 or its I equivalent, while the other. end member is pivoted upon the shaft 51, said shaft being provided upon its inner end with a pinion 52 located within the housing 53 and meshing with the rack bar 54 which carries the lamp socket 55; the housing 53 being slidably mounted upon the rods 49.

The shaft 51 is slidably and rotatably mounted through the adjacent end member 44 of the carriage and through the sleeve 56 carried by said end member 44, said sleeve being split at its outer end as shown at 57 and screw threaded for the purpose of receiving the nut 58 by means of which the sleeve may be clamped tightly upon the shaft 51 when the desired adjustment has been obtained, thus preventing sliding or rotating of the shaft. \Vith the construction above described the lamp, and the tilting frame thus provided, may be tilted bodily either forward or backward, upon the screw 50 and the rod 51 as pivots.

' The upper end of the rack bar 5% is provided with a disk 59 which is located between the under surface of the lamp socket and the perforated. disk 60 which is spaced from the lamp socket by means of the washer 61, said washer and disk 60 being attached to the lamp socket by means of screws 62 or their equivalents. The disk 59 is thus frictionally held between the under surface of the lamp socket and the perforated disk 60. By this constructionthe lamp socket can thus be adjusted radially upon the rack bar 5% in order to properly adjust the lamp to bring the filaments in a plane parallel with the reflector.

The lamp (33 is of any usual and well known construction, suitable for use in connection with a moving picture machine and is connected to the socket in the usual manner. A handle 64 is provided upon the socket by means of which the socket maybe turned upon the rack bar 54 in order to adj ust the lamp. A bracket 65 is connected to the rear upper portion of the lamp house by means of a bolt 66 or its equivalent and is provided with a horizontally disposed wall 67 through which the screw threaded rod 68 is mounted, said rod being provided with a knob 69 at its upper end; A yoke 70 is carried by the bracket 65. the free ends thereof being passed through the bosses 71 which are provided with set screws 72 for fixedly attaching the yoke to the bracket.

The plate 73 is provided with a horizontally disposed portion 74: at its upper end through which the upper end of the rod 68 is passed. a nut 75 being provided upon the lower end of said rod. 1 The plate 73 is provided with suitable bearings 76 and 77 which are slidably mounted upon the yoke 7 0. The lower end of the yoke is connected to the rear wall of the lamp house by means of a hook 7 8. It will thus be seen that by rotating the rod 68 the plate 73' maybe vertically moved upon the yoke 7 0.

The tube 7 9 is slidably mounted through a suitable aperture in the plate v '73 and is fixedly connected at its inner extremity to the boss 80 which is mounted at the upper extremity of the arm 81 which arm is integrally formed upon the channel 82. The rack bar 83 is fixedly connected to the boss 84 1113011 the channel 82, and passes-through the housing 85 within which is rotatably mounted the pinion 80, said pinion being fixed upon the rod 87, a knob 88 being provided upon the outer extremitypt' the rod for rotating the same.

A rod 89 is rotatably mounted Within the tube 79 and provided with a knob 90 at its outer extremity the inner extremity of said rod being screw threaded as shown M91 and located through the nut 92 carried upon the inner face of the boss 80, said rod being swiveled at its inner extremity to the knuckle 9.3, a link 94 pivotally connecting said knuckle with the knuckle 95 carried upon the post 96, which post is mounted upon the member 97, pivotally connected lent. 'A pair of dmvnwardly depending arms 101 are fixedly connected to the member 97 and provided with hooks 102 at their outer extremities, the reflector 103 resting upon said books. A curved wire 104 is connected to the post 96 at its lower end and provided with a hook 105 at its upper end which engages the upper edge of the reflector.

A tube 106 similar to the tube 79 is fixedly connected to the boss 10? carried by the horizontally disposed arm 108 which is formed integrally with the channel 82. A rod 109 is' rotatably mounted within said tube and provided with a knob 110 at the outer extremity, the inner end thereof being screw threaded and passed through the nut 111 carried upon the inner face of the boss 107. The knuckle 112 is swiveled upon the inner end of the rod 109 and is pivotally connected to the arm 113, which arm is rigidly connected to the bearing 99. It will be seen that the rear wall of the lamp house is slotted as shown at 11 1 to allow the tubes and rack bar above described to be moved vertically upon the lamp house.

In Figs. 8 to 10 inclusive is illustrated a modified form of the lamp carriage and reflector adjusting mechanism adaptable for use as a spot light. Yi ith this construction the reflector adjusting mechanism is carried upon the lamp carriage thus allowing the reflector and lamp to be moved together after the reflector has been adjusted without changingthe relative positions of the reflector and lamp.

The lamp carriage proper is of the same construction as that shown in Figs. 1, 2 and 3 with the exception that the rods 41'- upon which the carriage is slidably mounted ex tend the entire length of the lamp house, thus allowing greater adjustment of the lamp with reference to the lens. The casing 53 is provided upon each side with apair of alined lugs 120 through which. are mounted the screw threaded rods 121, the inverted U shaped member 122 being slidably mounted upon said rods and arranged to be locked in any desired adjustment by :means of a set screw 123.

The upper end of the UTSha-ped member 122 is provided with a bearing socket 124 within which is mounted -the lower extremity of the,post 125, a set screw 126 being provided to lock said 'post in any desired position. Upon the upperextremity of the post is carried a casing 127 similar in construction to the casing 53, said casing containing a pinion mounted upon a shaft 128 provided with an operating knob 129 at its outer extremity. This pinion meshes with the rack bar 130 upon the upper end of which is mounted the channel member 82'.

' The operating rods 91' and 109' and the tubes 79 and 106"within which said rods are mounted/are equivalent to the rods 91 and 109' and the tubes 79and 106 respectively which aretshown in Figs. 1 to 7 inelusive of the drawings with the exception that in the modified construction these rods and tubes are shorter, and the remainder of the reflector adjusting mechanism is of the same construction as that shoyvn in Figs. 1

to 7 inclusive.

For the pn ose ofadapting the construction shown in ig. 8 for use as a stereopticon device a horizontal rod 135 is connected to the front wall of the lamp house. A planeconvex lens 136 is mounted upon said rod by means of'the lug 137, a set screw 138 holding the lens in position. This plano-convex lens, in combination with the plano-convex lens 139 which is used for the spot light, producing the proper combination of lenses for use with the stereopticon device. A

stereopticon slide attachment 140 of the same arrangement as the slide attachment 135 is carried upon the frame of the lens 136. The usual stereopticon lens 18 is carried at the forward extremity of the rod 135, being provided with a lug 141 which engages the rod, a set screw 142 holding the same in position upon the rod.

When it'is desired to use the device as a spot light, the lenses 136 and 18 are swung upwardly upon the rod 135, the lens 139 being used for the spot light and when-it is desired to use thestereopticon device the lenses are swung down in the shown in, Fig. 8. c
